Food safety and science come together with these virtual labs. Students can see and practice some of the laboratory techniques used by researchers and food scientists. Visit the website to see eight virtual labs including Testing for Corn Mold, Bacteria Sampling, Gram Staining, Using the Microscope, The pH Scale and Meter Calibration, Testing and Adjusting pH, Understanding Water Activity, and Controlling Water Activity in Food.
What is water activity, and how does it affect food spoilage? In this virtual lab, students can explore how microbes and reactions inside food rely on water and calibrate a lab water activity meter. Students will become familiar with food science lab equipment and standard techniques for measuring water activity. The lab guides users through both theory and practice, preparing them for experiences in a real lab.
